I have the same problem. I can log in ok and veiw all the tabs apart from the play tab. As soon as this is picked it goes to the 100% icon but then never changes. Seems to be many people with the same issue. Is there anyone that can actually log in and play?

I have another topic about same matter if what Sansen have said does not help try here, and if it will not help then you ip has been banned by server for few time to go against DoS attack and you will have to try it later in around 3-4 hours time.
